- A cascaded ground source heat pump system links a central ground array infrastructure to a number of large modular ground source heat pumps cascaded together all in one central plant room.
- Cascaded ground source heat pump systems can adjust between minimum and maximum heat demand as needed.
- Cascaded systems can also be designed with one or more heat pump(s) dedicated to the production of domestic hot water only, and the remaining units dedicated to satisfy the space heating load.
- Cascaded ground source heat pumps reduce efficiency losses caused typically experience by alternative modulating heat pump designs.
- Cascaded ground source heat pump systems do not suffer downtime in the event of one unit requiring repair.
This page explores frequently asked questions about cascaded ground source heat pumps, their design, their benefits, and how to install them in large buildings with high heat demands.
